PERMUTATION-LOCK.

Specification of Letters Patent.

Patented June 29, 1909.

Application ined January i4, 1909. semi No. 472,358.

To all 'whom 'it may concern.'

Be it known that I, MATHEW SPINELLO, a citizen of Italy, residing at Kansas City, in the county of' Jackson and State of Missouri, have invented certain new and useful Improvements in Permutation-Iiocks; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the ar't to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a permutation lock and more particularly to a device of that class for use as a padlock.

It is the object of my invention to provide a device of that class which is simple in construction and operation, and comprises the improved details of structure hereinafter fully described and pointed out in the claims, reference being' had to the accompanying' drawings in which 5- Figure I is a view in elevation of a lock constructed according to my invention. Fig. II is a central longitudinal section of same, with the parts in their' locked position. Fig. III is a similar view with the parts in their unlocked position. Fig. IV is a cross sectional view on the line IV-IV, Fig. II. Fig. V is a similar view on the line V-/T, Fig. I.

Referring more in detail to the parts:-I designates the lock barrel which is cylindrical in formation and has a central channel extending longitudinally therethrough, the barrel being provided near one end with a keeper flange 2 which is preferably formed integral with the bar'rel, and at the opposite end with a threaded neck 3 which is adapted for carrying a removable flange 4 of the sarne diameter' as the flange 2.

5 designates tumbler rings which are adapted for rotation on the barrel 1 and are retained thereon by the keeper flanges 2 and 4.

Extending longitudinally in the barrel l is a slot 6 which communicates with the bar'rel channel and is` adapted for carrying a turnbler' bar 7, one end of which is provided with an inwardly projecting li 8 for a purpose presently setforth. The bar 7 is yieldingly tensioned outwardly by the compression springs 9, which seat against the inner' edge of said bar and against the side of the bar'rel opposite the slot 6. Each of the tumbler rings is provided with a slot l() which is adapted to register' with the barrel slot G and for receiving the tumbler bar when the latter is pressed outwardly by the. compression springs. The channel of one oi' .said rings is cam shaped, with the cani swell terminating flush with its slot I0 in order that when the parts ar'e in their' unlocked position and the ring is turned, the earn face will move over the locking bar and force saine inwardly against the tension el the springs 9, to enable the remaining rings to assume their locked relation to such bar. rIhe slots ol all of said rings are of like dimensions so that they may r'egister not only with the barrel slot but also each other, so that they may receive the tumbler bar ufhen'brought into broper relation with each other and with the barr'el slot.

Il designates a lock arm which `is rigidly connected with one end of the barrel l by means of a screw .l2 which projects through an aperture in said arm and is threaded into the adjacent end ol the barrel cylinder.

Pivoted to the arm l] is a shackle member 13, the free end of which has an aperture through which the tumbler pin let is adapted to project, the inner end ol the pin extending a short distance into the barri'd cylinder and being provided with a groove l5 into which they lip S on the tumbler bar is adapted to seat, in order to anchor the pin against longitudinal displacement.

The peripheries of the tumbler rings are polygonal and each individual vliace of the rings is provided with a suitable numeral in order that a proper combination ol the rings may be made to secure regisi rationell the inner slots of the rings.

In assembling my improved lock, the ring 5 having the cam groove l5 is first fitted onto the barrel and so turned that the body ol'v the ring will engage the tumbler bar and depress saine against the tension oll the springs t), so that the remaining rings may be fitted over the barrel without the necessity ol depressing the tumbler bar or ol 'litting the slotted ring sections thereover. ifrl'ter the rings are in place the keeper llange -l is threaded onto the barrel neck andl the pad lock arm secured thereto, a rivet pin lo being preferably extended through the barrel neck and screw I2 in order to jun'nutnently fiX the parts. The tumbler rings all turned to their unlocking combination in which all of their' inner slotted sections are in line, so that the tumbler bar may be projeoted into the groove formed by 'the combined ring sections. The locking pin 14 is then projected through the shackle aperture and through the barrel channel until the groove l5 is in position for receiving the projecting lip of the tumbler bar. By turning the ring 5, having the cam channel 15, the tumbler bar is moved inwardly against the tension of the springs 9 until it `is free ol the slotted ring sections and the rings are free to move independently on the barrel l, the tumbler bar being forced inwardly until the lip 8 seats in the locking pin and holds same against longitudinal displacement, the pin head 14/ holding the shackle 13 to the barrel 1. lt is readily apparent that when the tumbler rings are again turned to their unlocking combination, the springs 9 will force the bar 7 into the slotted ring sections, so that the pin la is released from the bar lip in order that Vit may be removed and the shackle turned on its pivot.

With a lock of this character' the tumbler bar is held in its locking position as long as the slotted section of a single ring is out of registration with the sections of the remaining rings, so that in order to unlock the device, all of the tumbler rings must be in their proper position.

Having thus described my invention, what l claim as new therein and desire to secure by Tnett-ers Patent is l` A permutation lock comprising a barrel having an elongated longitudinal slot, a tumbler bar adapted for radial movement in said slot, tumbler rings adapted for rotation on said barrel and provided with slotted sections adapted for receiving said bar, a shackle, and a pin adapted for projection through a portion of said shackle into said barrel and for interlocking engagement with said tumbler' bar.

2. ln a permutation lock, a barrel having a longitudinal slot, rings revolubly mounted on said barrel and provided with slots adapted for registration with each other and with said barrel slot, a tumbler bar adapted for radial movement in said barrel slot and for proj ection into the ring slots, springs located in the barrel chamber and yieldingly tensioning said bar toward its ring engagement, and a pin adapted for projection into said barrel, said bar being provided with a locking lip and said pin with a groove for receiving said lip, substantially as and for the purpose set forth.

3. ln a permutation lock, a barrel having a longitudinal channel and a slot opening through the barrel side'and communicating with said channel, and a keeper flange integral with the barrel body and projecting from near one end thereof, rinO's revolubly mounted on said barrel and havin@I slots adapted for registration with each other and with the barrel slot, a keeper threaded on to said barrel at the end opposite said ilange, a lock arm permanently mounted on said barrel, a shackle pivotally mounted on said arm and provided with an aperture in its free end, a pin adapted for projection through said shackle aperture and into the barrel channel and provided with a lip receiving groove7 a tumbler bar adapted for radial movement in the barrel slot and in the ring slots, and a lip on said bar adapted For projecting into the groove in said pin, substantially as and for the purpose set forth.

4t. ln a permutation lock, a. slotted barrel, having end iianges, rings revolubly mounted on said barrel between said end liangcs and provided with slots adapted for registration with each other and with the barrel slot to form an elongated channel for a tumbler bar, a tumbler bar located in said barrel and having a bony portion adapted for movement into and from said channel, a shackle pivoted at one end of said barrel and provided with an aperture at its free end, and a pin adapted for projection through the aperture in said shackle and into said barrel, said pin being provided with a head at its free end and with means on its inner end for interlocking with said tumbler bar.

5. In a permutation lock, a slotted barrel having an integral iiange at one end, and a threaded neck at the opposite end, slotted tumbler rings adapted for revolution on said barrel, a flange having threaded connection with the barrel neck and adapted lor retaining said rings on said barrel, an arm secured to said barrel neck, a shackle pivoted on said arm and provided with an aperture at its free end, a pin adapted .tor extension through the shackle aperture into said barrel, a tumbler bar adapted for locking engagement with said pin and for movement into the barrel slot and ring slots, and springs adapted for moving said bar into said slots and out ot' locking engagement with said pin.

6. ln a permutation lock, a slotted barrel, having a keeper flange at each end, a tumbler bar adapted for movement in the barrel slot, a shackle, having one end pivoted to said bar and provided with an aperture at its tree end, a pin adapted tor projection through the shackle aperture into said barrel and for locking engagement with said tumbler bar, and tumbler rings revolubly mounted on said barrel and provided with slots Vfor recoiving said tumbler bar, one of said ngs be' ig cut away on its inner surface to form a cam path to the bottom ot said slot, substantially as and for the purpose set forth.
